Comment
Energise for high revs
Analogue output to propor-
tional valve
High when engine start/run is
allowed
High to active glow plug relay
High to turn engine starter
motor
To steer left energise
MM:SV1a & MM:SV4
To steer right energise
MM:SV1b & MM:SV4
To tilt platform left energise
MM:SV2a & MM:SV4
To tilt platform right energise
MM:SV2b & MM:SV4
To tilt platform forward ener-
gise MM:SV3a & MM:SV4
To tilt platform backwards en-
ergise MM:SV3b & MM:SV4
Energise to allow platform
levelling and steering
To lift platform energise
MM:SV5 and proportional
valve MM:SP1
*Solenoid on lift cylinder
For low speed forward drive
energise DM:SV01a and pro-
portional valve MM:SP1
For low speed reverse drive
energise DM:SV01b and pro-
portional valve MM:SP1
gise DM:SV4 & DM:SV8 and
select forward/reverse with
DM:SV01a/DM:SV01b and
proportional valve MM:SP1
For high speed drive energise
DM:SV5, DM:SV8, DM:SV11
& DM:SV13 and select for-
ward/reverse with DM:SV01a/
DM:SV01b and proportional
valve MM:SP1
Energised for high & medium
speed drive
